The short explanation
No, a slightly raised CA-125 does not mean you have ovarian cancer. CA-125 is a protein that can rise for many reasons that have nothing to do with cancer, such as periods, endometriosis, fibroids, pelvic infection, pregnancy, liver disease and even some lung or heart conditions. In women who still have periods, a mildly high result is especially common and often harmless. This is why CA-125 is not recommended as a screening test for women without symptoms. It can cause a lot of worry without being reliable. A doctor will look at your age, symptoms and history, and may suggest a pelvic ultrasound or a repeat test to understand the result.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- CA-125 is more useful in women with symptoms, a pelvic mass on a scan, or for monitoring someone already being treated for ovarian cancer.
- Results can vary with the timing of your menstrual cycle, so a repeat test may be timed carefully.
- A family history of ovarian or breast cancer may change how the result is followed up.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you why your CA-125 is raised. Your doctor will decide whether further tests are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How high is my CA-125, and how much does it concern you?
- Do I need an ultrasound?
- Should the test be repeated, and when?
- Could endometriosis or fibroids be the cause?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a doctor within a week or two to discuss the result, especially if you develop bloating, pelvic pain or early fullness.
Raise it at a routine appointment
- Book a routine follow-up to decide whether a scan or repeat test is needed.
